换算刚度法是近几年提出并得到较快发展的结构分析方法,它的主要特点是根据不同的结构形式,适当地引进结构的换算刚度,可使多跨结构的高次超静定问题,变成单跨结构来求解。从而,大大地简化计算手续,使一些比较复杂的问题变得简单。特别是在许多桥梁结构的内力分析中,具有明显的优越性。除连续梁的内力分析之外,还能成功地计算连续拱桥及其他多跨结构。
The conversion stiffness method is a structural analysis method that has been proposed in recent years and has been developed rapidly. Its main feature is that according to different structural forms, the conversion stiffness of the structure is properly introduced, and the high-order statically indeterminate problem of the multi-span structure can be solved. Become a single span structure to solve. This greatly simplifies the calculation procedures and makes some of the more complex problems simple. Especially in the internal force analysis of many bridge structures, it has obvious advantages. In addition to the analysis of the internal forces of continuous beams, continuous arch bridges and other multi-span structures can be successfully calculated.
